* Camellia 128 / 192 / 256 encryption.
*
* 16, 24 or 32 bytes key, 16 byte IV
*
* Example:
* ```
* const cipher = new CAMELLIA();
* // Key for browser
* const encoder_key = new TextEncoder();
* const key = encoder_key.encode("0123456789ABCDEF");
* cipher.set_key(key)

* const key = Buffer.from("0123456789ABCDEF");
* cipher.set_key(key)
* // set IV for browser
* const encoder_IV = new TextEncoder();
* const IV = encoder_IV.encode("0123456789ABCDEF");
* cipher.set_iv(IV)
* // set IV for node
* const IV = Buffer.from("0123456789ABCDEF");
* cipher.set_iv(IV)
* // Encrypt for browser
* const encoder_text = new TextEncoder();
* const text = encoder_text.encode("test text");
* const text_length = text.length
* const ciphertext = cipher.encrypt(text)
* // Encrypt for node
* const text = Buffer.from("test text");
